1) 1 Sheet frozen puff pastry (half of 17.3 oz. package), thawed
2) 3 bacon slices, cut crosswise into 0.5 inch pieces
3) 0.25 cup of honey
4) 0.25 cup of dry white wine
5) 2 large sweet yellow onions (about 680gr), cut into 0.25 inch
thick rounds
6) Nonstick vegetable oil spray
7) 0.75 cup crème fraiche
8) 0.5 teaspoon fine sea salt
9) 1/8 teaspoon freshly grated nutmeg
10) 1 teaspoon fresh thyme leaves
Steps
1) Position rack in top third of oven and preheat to 375ºF / 190ºC.
2) Using lightly floured rolling pin, roll out puff pastry on lightly
floured surface to 14x10 inch rectangle. Fold 0.5 inch of pastry edges
in toward center on all sides, forming 13x9 inch rectangle.
Transfer pastry to large rimmed baking sheet. Press firmly on pastry
edges with form to form rim. Chill crust.
3) Cook bacon in small skillet over medium heat until brown and crisp.
Transfer to paper towels and drain. Reserve 1 tablespoon of bacon
drippings from skillet.
4) Whisk honey, wine, and reserved bacon drippings in a large bowl. Add
onions and toss to coat.
5) Coat another large rimmed baking sheet with nonstick spray. Spread
onion mixture in even layer on sheet. Roast 30 minutes.
Turn onions over, allowing rings to separate. Roast until onions are
caramelized, turning often for even browning, 30-45 minutes.
Remove from oven and let cool slightly.
6) Increase oven temperature to 400 degrees.
7) Mix crème fraiche, sea salt, 0.25 teaspoon of black pepper, and
nutmeg in a small bowl. Using offset spatula, spread crème fraiche over
curst to folded edge and arrange onions on top. Sprinkle with bacon.
8) Bake tart until crust is light golden brown and topping is bubbling,
20-25 minutes. Sprinkle with thyme and serve.
Notes
1) Some issues with dough not cooking fully, try cooking dough for a few
minutes before adding crème and onions.
2) Add more onions!
3) Substitute crème for goat cheese and bacon for vegetables.
